That's? Not how it works. Dominant does not equal overriding your partner's boundaries, it does not automatically equate to being mean or mischievous (because there are different ways to be dominant in a Dom/sub dynamic).
Ash giving Lyle a safeword (including the kiss on the cheek) that he doesn't believe Lyle would be comfortable using IS actually him putting obstacles for Lyle to revoke his consent. This is fictional, but in real life that would very possibly land in SA territory, very quickly. Obviously Lyle has mentioned that he is into it, but that doesn't change the fact that we haven't really seen proof that ash would respect a "no" if Lyle wasn't comfortable or did choose to use a safeword.
They're in love, yes, but they're not actually practicing safe sexual habits, at all.

no?? he has said from his POV multiple times he'd always stop of lyle actually hates it. Novel gives u more perspective but even in the manhwa lyle "enjoys" this aggressive side of ash during their intercourse. He's not an ass and isn't pushing any intimate or dubious boundaries and won't in the future, he actually set a safe word too + communicated with lyle. You need to know they're not any new people getting into a new relationship but already in an established one, their boundaries are more comfortable and less strict especially with how many times they've had sex and communicated from both sides on how they like it and what both can handle, ash isn't forcing himself on lyle and lyle enjoys the way ash is, ash knows that, lyle knows him too. Its pretty well written and very realistic in many senses. Just because lyle is embarrassed doesn't mean he's against it, both of them have been established to know this thing, just because ash is dominant and aggressive doesn't mean he's forcing lyle, again, both are aware of this fact. You'll love the novel in my opinion, it gives an even detailed explanation on their thoughts but both of them lovingly accept each as it is and communicate not just through words but ALSO actions.

If you actually read what I posted you'll see that I never said that his boundaries had actually been crossed. You were the one who said "because he's the dominant one" in response to someone feeling as though Ash is being overly pushy. That's the part I was responding to.
I stand by my point that they're not practicing safe D/S habits. That can be the case whether both parties are of equal strength or not – which, by the way, should not matter. You shouldn't have to be in a position with your partner where you HAVE to use your physical strength to get your partner to stop, but that's the inplication you're making when you say "he can handle himself." The entire point is that safewords and/or "no" should be accessible for both parties at any and all time, and that it should result in an immediate stop.
But as I said, I recognise that this is fictional, but a dynamic like this irl could end very badly. That was my conclusion.

Bro I'm not . You misunderstood my comment to begin with when I said Ash is dominant I meant one of them has to take the initiative to make their s*x more interesting that's all and from previous chapters they have already tried sex toys that Lyle wasn't a big fan of but this isn't anything new in their relationship

But that's not what being dominant is; that's literally the point. It's not like there's an end goal to sex where you have to have the kinkiest sex for it to be fulfilling. That's why it's important to actually sit down with your partner and discuss what your limits, fantasies and curiosities are. ash proposing safewords that he's aware karlyle won't feel comfortable using is not enough and is not safe BDSM OR safe D/S dynamics.
If your partner doesn't want to do something, it's not your responsibility OR right to push that onto them. Not my force, not by trickery, not through games – neither of those three imply consent. It doesn't matter that you're the one taking the most initiative in the relationship, it's still not acceptable D/S habits. Being dominant does not override basic consent. Obviously.
Ash is sorta an ass right? He keeps doing stuff Lyle doesn't wanna do
